Key Features

1
1. Reliable Operation in High-Current InstallationsThe ABB UA16-30-10RA is designed to handle peak currents far exceeding 100 times nominal rms current, making it ideal for high-power capacitor duty applications.
2
2. Built-in Damping ResistorsEquipped with three damping resistors, this contactor limits the current peak during energization of the capacitor bank, ensuring safe and efficient operation.
3
3. High Electrical DurabilityWith an electrical durability of 250,000 operating cycles for Ue < 500V and 100,000 cycles for 500V ≤ Ue ≤ 690V, this contactor offers long-lasting performance in demanding environments.
4
4. Block-Type Design for Enhanced PerformanceThe block-type design of the UA16-30-10RA ensures serial insertion of damping resistors, which limits the second current peak upon making of the main poles, enhancing overall electrical safety and efficiency.
